Answer:
3x+3=-36 is the equation
The answer is -13,-12,-11
Step-by-step explanation:
So consecutive integers, so lets say it’s x, if it’s consective it means the next number after, (Ex: 1,2,3,4,5) so the pattern is x+x+1+x+2 and so on. In this a
cade it’s 3 numbers so x+x+1+x+2 which is 3x+3.
Were trying to find -36 so 3x+3=-36
Solve the equation and you’ll get -13.
Add 1 to -13 and add 2 to -13 and you have your 3 consecutive numbers!
-13+1=-12 -13+2=-11. The original is -13
check: -13+-12+-11=-36 is correct
The equation is
3x+3=-36

Answer:
450 students
Step-by-step explanation:
Let s = number of students
1/2 are Americans 1/2s are Americans
s -1/2s = number of students left
1/2 s = number of students left
1/3 of the students left are Europeans
1/3 (1/2s) = 1/6s are Europeans
The rest are Australians = 150
Students = Americans + Europeans + Australians
s = 1/2s + 1/6s + 150
Combine like terms
s = 1/2*3/3 *s + 1/6s +150
s = 3/6s + 1/6s +150
s = 4/6s + 150
Subtract 4/6s from each side
s -4/6s = 150
6/6s - 4/6s = 150
2/6s = 150
1/3s = 150
Multiply each side by 3
3* 1/3s = 150*3
s = 450
There are 450 students
The answer is D M=wh which means for every hour or H he get payed w multiply w*h to get how much money he gets in all or M<span />
